Warrant Officer Candidate School?

I am a Sergeant in the NC Army National Guard. I was recently accepted into the active duty Warrant Officer Flight Program (WOFT) and report to Warrant Officer Candidate School in a few months. It has been 5 years since basic and AIT and almost 2 years since I came home from Iraq. I am a little apprehensive about going back on active duty. Can anybody give me any advice on preparing for the school that have attended WOCS? Please be specific about the school. Is it like a basic training environment? Do you get time off to see your spouse while in WOCS? How difficult is the training? Please no “If you want it bad enough….” comments. These aren’t helpful at all and are a waste of both my time and yours. Thanks.
